That is fundamentally the point I try to make, the wing compresses air, and does so in such a way as to create a very real and bordered system. Because air has mass, and seeks to equilibrate, a dynamic force lifts the wing. The system is constantly being destroyed, and created.
The zone of low pressure above the wing is a byproduct of compression up stream, and as a result of process, cannot be said to be its initiator. Bernoullians want folks to look at the magic of low pressure, and at its captivating creation by "accelerating" the air mass, locally. Fine, so far, but there is no "magic", lift takes work, hard noisy work, and if one wants to lift, one must stay moving. One must look at Newton to describe the system, Bernoulli describes local artifacts not the system.
The 'held in place' cambered section diagram is the recipient of airflow, not its creator. A flat plate is no different, they both produce lift by compressing air at the leading edge, both above and beneath it.
"A and E", in their paper, completely destroy the arse-about paradigm that the "shape" (section) of an airfoil makes some kind of basic difference in the fundamental Laws that create Lift.
